What is the ruling on a wife remaining with a husband who is unemployed, neglects himself, his home, and his children, and is only preoccupied with the internet, especially with suspicions that he is afflicted by magic?

The questioner should pray and supplicate to Allah, be patient with her situation, thank Allah for His blessings, and look to those who are less fortunate than her. Both she and her husband should seek treatment if they believe he is afflicted by magic. If she is harmed by remaining with him, she has the right to seek a divorce due to harm, or resort to khul'.
